AC-DC Power Supplies Confi gurable TypeInstruction Manual3.15 Alarm!The unit has two typs of alarm below. Table 3.3 is the detail of thealarm.1PR: abnormal input voltage, fan alarm2LV: drop and shut-off of output voltagePRLVTable 3.3 Explanation of alarmsAlarmWhen the input voltage isabnormal (low input voltage) orthe fan stops, the alarm signal isgenerated from CN1.When the rated output voltagedecreases or stops, the alarmsignal is generated from CN3.Note:When the overcurrent protectionactivates, the alarm will beunstable.Output of alarmOpen collector methodGood:Low (0.5Vmax at5mA)Fail:High (50Vmax)Open collector methodGood:Low (0.5Vmax at5mA)Fail:High (50Vmax)The alarm circuits (PR and LV) are isolated from others (the input,outputs, FG, AUX and other function terminals).When the DC-DC converter is connected to the AUX, the currentmight be severalfold of the normal current when starting up.Please check the current.!The maximum external capacitor to the AUX is 47μF.3.17 Medical Isolation grade!AME series meets 2MOPP2MOPPPrimary Secondary1MOPPSafety GNDFig.3.10 Medical Isolation Grade0.1mF 100kWFig.3.8 PR internal circuit0.1mF 100kWPRPRGLV4 Peak Current(Applying module : G4, G, H4, H, U, P, Q, 2C, 2D, 2M)!Some output modules have the peak capability of the followingconditions.-t1[5sec-Ip[Rated peak current-Iave[Rated currentt1-Duty= X100 [%] [ 35%t1+t2LVGFig.3.9 LV internal circuit!Please note the followings when you use the alarm (LV signal).1 If the output voltage is turned off by the remote ON/OFF circuit,the LV signal will get“High”.2 If the output voltage drops below the lower limited of adjustmentrange, the LV signal may get“High”.3.16 Auxiliary power (AUX)!The unit has the auxiliary power (AUX: 5V1A) in CN1 to providefor the remote ON/OFF and external circuits.!When the Global inhibit function activates, the following deratingfor the AUX is required.Derating for AUX: Io(AUX) [ 0.5A!The AUX circuit(AUX, AUXG) is isolated from the input, outputs,the FG, and other function terminals except GI1.!If the output current of the AUX exceed 1A, the unit might be damagedor malfunction.[A]Output currentIp : Peak currentIave : Average currentI : Load currentt1 t2Fig.4.1 Peak current!Derating curve for input voltageThe derating curves with respect to input voltage are shown in“Derating”.AME-19
